OK, let's examine this...."parks have closed". What? How did that happen? Parks are managed areas of grassland, pasture, wilderness and sports facilities and are not sentient beings. They cannot make a decision to opencloseexpandretreat etc etc.
IBC manages the parks in Ipswich and that entity alone bears all responsibility.
The simple addition of the word "have", as in "have been closed" would have saved the day!
